Funções gerenciais na gestão educacional : caracterização do trabalho gerencial dos gestores da Secretaria Municipal de Educação de Santa Maria de Jetibá-ES

Esta pesquisa tem a intenção de descrever as características do trabalho gerencial de gestores educacionais, iniciando-se de estudo realizado com gestores escolares, coordenadores pedagógicos que atendem às escolas multisseriadas da secretaria de educação do município de Santa Maria de Jetibá (ES). Buscou-se caracterizar a ação gerencial desses gestores partindo das percepções deles sobre os trabalhos realizados junto aos demais membros da comunidade escolar, equipes de gestão e gestão da secretaria municipal, não deixando de lado as particularidades da área educacional, principalmente sobre gestão democrática e autonomia. Para se entender a diversidade, a complexidade e as dinâmicas relações dos gestores, foram realizadas entrevistas semiestruturadas que contribuíram para aprofundamento nessas dinâmicas. Documentos foram analisados para conhecimento e caracterização da formatação da estrutura organizacional da secretaria de educação. Os relatos das entrevistas apresentaram fragmentos que puderam nortear ideias para um melhor tratamento dos dados, que foram realizados analisando os conteúdos apresentados pelos gestores entrevistados. As conversas realizadas com esses entrevistados mostraram ambiguidade, dinamismo e pluralidade no desenvolvimento das “funções gerenciais” dos gestores educacionais, que são líderes, companheiros e executores de trabalhos junto aos demais componentes das relações do ambiente educacional. Assim, as expectativas são de que esta pesquisa possa fazer com que novos diálogos surjam para discutir as relações dos gestores educacionais, principalmente sobre as ações dos coordenadores que atuam junto às escolas multisseriadas.

Práticas e saberes da professora pomerana : um estudo sobre interculturalidade

Esta pesquisa analisa práticas e saberes da professora pomerana em uma escola do campo de ensino fundamental em Santa Maria de Jetibá/Estado do Espírito Santo/Brasil, para problematizar questões sobre cultura e interculturalidade. Aprofundam-se reflexões sobre quais têm sido as contribuições dessas práticas para uma educação escolar intercultural. Beneficia-se do estudo de caso para análise de documentos, observações de aulas, observações participantes em planejamentos, realização de entrevista semiestruturada com a professora e, anotações no diário de campo. Situam-se brevemente questões da história dos descendentes de pomeranos, bem como sobre as principais produções acadêmicas referentes à educação desse povo tradicional. Discussões teórico-metodológicas contribuem para compreensão e embasamento de alguns conceitos-chave, como: cultura(s) (THOMPSON, 1995; GEERTZ, 2012), interculturalismo (CANDAU, 2005; FORNET-BETANCOURT, 2004), cultura escolar e cultura da escola (FORQUIN, 1993), práticas docentes (FREIRE, 1996), saberes docentes (TARDIF, 2012), parceria (FOERSTE, 2005) etc. Aponta-se que as práticas da professora pomerana faziam parte do contexto escolar antes da implementação do Programa de Educação Escolar Pomerana (PROEPO) no que se refere ao uso oral da língua pomerana na sala de aula. As práticas da professora se ressignificam na interação com os saberes culturais, experienciais e coletivos produzidos na dinâmica escolar e comunitária. Essas práticas possibilitam o diálogo da cultura escolar com a cultura da escola, promovendo a vivência das experiências locais e o acesso ao saber universal. Pode-se afirmar que no contexto da escola investigada existem algumas condições que favorecem a dimensão da interculturalidade nos processos pedagógicos. Cabe aprofundar estudos sobre as contribuições da educação escolar para o ensino bilíngue e seus impactos à valorização da cultura pomerana e a consequente manutenção da língua deste povo tradicional. Tensões e conflitos foram identificados quanto ao enfoque do PROEPO ao desenvolvimento das habilidades de leitura e escrita em língua pomerana.

Práticas corporais na comunidade tradicional Alto Santa Maria : continuidades e descontinuidades

O objetivo do estudo foi identificar jogos, danças, brincadeiras e outras práticas corporais para analisar o processo de sua apreensão pelos sujeitos nas dinâmicas de relações sociais das comunidades. Em menor instância, os objetivos foram listados para analisar os momentos de continuidade, descontinuidade e/ou ruptura das tradições que ocorrem ao se desenvolver as práticas corporais e identificar e analisar as relações registradas nos espaços de “entrega” e “recepção” dessas tradições. Para tanto, ao propor a investigação das práticas corporais de comunidades tradicionais como nosso objeto de estudo, decidimos analisar Alto Santa Maria, do estado do Espírito Santo, localizada no município de Santa Maria de Jetibá, elegendo como sujeitos deste estudo crianças e adultos da comunidade pomerana. A partir de uma abordagem qualitativa, num primeiro momento foi realizado um levantamento bibliográfico e, posteriormente, o trabalho em campo para a coleta de dados por meio de entrevistas abertas e da técnica de observação assistemática de campo. A análise das entrevistas foi realizada de forma interpretativa, buscando apreender nas falas dos sujeitos, e de forma qualitativamente satisfatória,as categorias previamente selecionadas. A análise dos dados permitiu reconhecer, dentre os vários elementos da identidade cultural, a cultura corporal com relaçãoàspráticas corporais locais. Em Alto Santa Maria, elas se inscrevem em um contexto dinâmico, no qual se registram tanto tradicionais quanto não-tradicionais. Desta forma, concluímos que as práticas corporais, como jogos, brincadeiras e danças, materializam-se, nos contextos descritos, simultaneamente como práticas pomeranas ou externas à comunidade, mas que hoje fazem parte das práticas culturais do Alto Santa Maria, conduzindo a um diálogo entre elas.

Climate governance in an international system under conservative hegemony: the role of major powers

In the last five years, climate change has been established as a central civilizational driver of our time. As a result of this development, the most diversified social processes - as well as the fields of science which study them - have had their dynamics altered. In International Relations, this double challenge could be explained as follows: 1) in empirical terms, climate change imposes a deepening of cooperation levels on the international community, considering the global common character of the atmosphere; and 2) to International Relations as a discipline, climate change demands from the scientific community a conceptual review of the categories designed to approach the development of global climate governance. The goal of this article is to discuss in both conceptual and empirical terms the structure of global climate change governance, through an exploratory research, aiming at identifying the key elements that allow understanding its dynamics. To do so, we rely on the concept of climate powers. This discussion is grounded in the following framework: we now live in an international system under conservative hegemony that is unable to properly respond to the problems of interdependence, among which - and mainly -, the climate issue.

An outline of military technological dynamics as restraints for acquisition, international cooperation and domestic technological development

The expectation that technological returns from defense expenditure through acquisition, international cooperation and domestic research would further national development underappreciates the different technological dynamic of the armed services. This paper outlines the technological dynamic the stems from fighting in the air, at sea and on land, exemplifying consequences for the case of acquisition.

Molecular dynamics computer simulation of scratch resistance testing of polymers: visualization

Experimental scratch resistance testing provides two numbers: the penetration depth Rp and the healing depth Rh. In molecular dynamics computer simulations, we create a material consisting of N statistical chain segments by polymerization; a reinforcing phase can be included. Then we simulate the movement of an indenter and response of the segments during X time steps. Each segment at each time step has three Cartesian coordinates of position and three of momentum. We describe methods of visualization of results based on a record of 6NX coordinates. We obtain a continuous dependence on time t of positions of each of the segments on the path of the indenter. Scratch resistance at a given location can be connected to spatial structures of individual polymeric chains.

Polymer indentation with mesoscopic molecular dynamics

Indentation tests are used to determine the hardness of a material, e.g., Rockwell, Vickers, or Knoop. The indentation process is empirically observed in the laboratory during these tests; the mechanics of indentation is insufficiently understood. We have performed first molecular dynamics computer simulations of indentation resistance of polymers with a chain structure similar to that of high density polyethylene (HDPE). A coarse grain model of HDPE is used to simulate how the interconnected segments respond to an external force imposed by an indenter. Results include the time-dependent measurement of penetration depth, recovery depth, and recovery percentage, with respect to indenter force, indenter size, and indentation time parameters. The simulations provide results that are inaccessible experimentally, including continuous evolution of the pertinent tribological parameters during the entire indentation process.

Simulating scratch behavior of polymers with mesoscopic molecular dynamics

Part replacement and repair is needed in structures with moving parts because of scratchability and wear. In spite of some accumulation of experimental evidence, scratch resistance is still not well understood. We have applied molecular dynamics to study scratch resistance of amorphous polymeric materials through computer simulations. As a first approach, a coarse grain model was created for high density polyethylene at the mesoscale. We have also extended the traditional approach and used real units rather than reduced units (to our knowledge, for the first time), which enable an improved quantification of simulation results. The obtained results include analysis of penetration depth, residual depth and recovery percentage related to indenter force and size. Our results show there is a clear effect from these parameters on the tribological properties. We also discuss a "crooked smile" effect on the scratched surface and the reasons for its appearance.

Pectus Excavatum postsurgical outcome based on preoperative soft body dynamics simulation

Pectus excavatum is the most common congenital deformity of the anterior chest wall, in which an abnormal formation of the rib cage gives the chest a caved-in or sunken appearance. Today, the surgical correction of this deformity is carried out in children and adults through Nuss technic, which consists in the placement of a prosthetic bar under the sternum and over the ribs. Although this technique has been shown to be safe and reliable, not all patients have achieved adequate cosmetic outcome. This often leads to psychological problems and social stress, before and after the surgical correction. This paper targets this particular problem by presenting a method to predict the patient surgical outcome based on pre-surgical imagiologic information and chest skin dynamic modulation. The proposed approach uses the patient pre-surgical thoracic CT scan and anatomical-surgical references to perform a 3D segmentation of the left ribs, right ribs, sternum and skin. The technique encompasses three steps: a) approximation of the cartilages, between the ribs and the sternum, trough b-spline interpolation; b) a volumetric mass spring model that connects two layers - inner skin layer based on the outer pleura contour and the outer surface skin; and c) displacement of the sternum according to the prosthetic bar position. A dynamic model of the skin around the chest wall region was generated, capable of simulating the effect of the movement of the prosthetic bar along the sternum. The results were compared and validated with patient postsurgical skin surface acquired with Polhemus FastSCAN system

Network dynamics in scientific knowledge acquisition: an analysis in three public universities in the state of Bahia

This paper aims to cast some light on the dynamics of knowledge networks in developing countries by analyzing the scientific production of the largest university in the Northeast of Brazil and its influence on some of the remaining regional research institutions in the state of Bahia. Using a methodology test to be employed in a larger project, the Universidade Federal da Bahia (UFBA) (Federal University of Bahia), the Universidade do Estado da Bahia (Uneb) (State of Bahia University) and the Universidade Estadual de Santa Cruz (Uesc)'s (Santa Cruz State University) scientific productions are discussed in one of their most traditionally expressive sectors in academic production - namely, the field of chemistry, using social network analysis of co-authorship networks to investigate the existence of small world phenomena and the importance of these phenomena in research performance in these three universities. The results already obtained through this research bring to light data of considerable interest concerning the scientific production in unconsolidated research universities. It shows the important participation of the UFBA network in the composition of the other two public universities research networks, indicating a possible occurrence of small world phenomena in the UFBA and Uesc networks, as well as the importance of individual researchers in consolidating research networks in peripheral universities. The article also hints that the methodology employed appears to be adequate insofar as scientific production may be used as a proxy for scientific knowledge.

A System Dynamics-Based Simulation Experiment for Testing Mental Model and Performance Effects of Using the Balanced Scorecard

This study develops a theoretical model that explains the effectiveness of the balanced scorecard approach by means of a system dynamics and feedback learning perspective. Presumably, the balanced scorecard leads to a better understanding of context, allowing managers to externalize and improve their mental models. We present a set of hypotheses about the influence of the balanced scorecard approach on mental models and performance. A test based on a simulation experiment that uses a system dynamics model is performed. The experiment included three types of parameters: financial indicators; balanced scorecard indicators; and balanced scorecard indicators with the aid of a strategy map review. Two out of the three hypotheses were confirmed. It was concluded that a strategy map review positively influences mental model similarity, and mental model similarity positively influences performance.

Strategy Lab Experiences: Bathtub Dynamics

As the world changes ever faster, managers increasingly recognize the complexity and turbulence of the business systems in which they are embedded. The management problems are dynamic, while the dynamic complexity comes frequently from few variables with circle and delays interrelations that introduce nonlinearities.The present paper describes a research conducted in Portugal with two different groups - one, academic; the other, professional - where we explored the subjects’ understanding of some basic systems thinking concepts such as stock-flow relationship, feedback processes and time delays.
